8 Notices for the operation in winter

(1) If the temperature is low in winter and the unit hasn't been started up for a
long time, energize the unit for at least 8h before turning on the unit.
(2) If the outdoor temperature is low in winter, do not cut off the power if the unit
stops operation for a short time. Otherwise, the auto freeze prevention
protection will be invalid. Under the low temperature circumstances, the auto
prevention protection will be active when the water temperature inside the
water tank is closing to freezing point, and it will be stopped when the water
temperature inside the water tank rises to the safe temperature. However, the
auto freeze protection function for the water tank is not unavailable for water
inlet pipe and water outlet pipe. If the temperature at the installation position
for the unit is lower than 0℃, the antifreezing heating belt must be installed at
the pipeline and it should be at the energized status. If the water tank must be
installed at outside, the pipe at the outdoor side should be as short as
possible, including the connection pipe of refrigerant and the water inlet pipe
and water outlet pipe for the water tank; otherwise, the heat will be lost too
much; What's more, too much will be lost and the water system will be frozen.
Meanwhile, the connection position for the valve and bending position for the
water pipe must be insulated well.
(3) If the unit won't be used for a long time, please drain out the water inside the
water tank and pipeline completely. Otherwise, the water system will be
frozen. After water is drained out completely, if operate the unit again, fill up
the water tank with water and then the unit can be turned on. Please refer to
the water replenishing and water drainage for water tank for details.
Warm hint:
If it's not convenient for operation or there's hazard, please contact the local
appointed dealer or appointed service center directly. We will appoint profession
persons to check, debug and clean the unit, and discharge water and fill the water
tank with water for you.
